DuoDom — the laid-back sliding puzzle in pixel-art retro style. A board fills with stones marked 1 to 6. Slide them across the empty squares so that two matching stones land right next to each other — they vanish as a pair. Clear the whole board to win. HOW TO PLAY • Tap a stone to select it. • Tap an empty neighbouring square to slide the stone there. • When two matching stones meet edge to edge, they disappear. • Clear the entire board — level done. Every puzzle is guaranteed solvable — a built-in solver verifies each level before you see it. No frustration, no dead ends. FEATURES • Hundreds of solver-checked puzzles • Pixel-art graphics in lovingly crafted retro style • Smooth animations at 60 FPS • Per-level highscores — how few moves can you do it in? • Trophy system for special achievements • Built-in tutorial • Pause with settings for volume and language • Synthesized sound effects straight from the game • Works in any screen size, portrait and landscape 20 LANGUAGES DuoDom auto-detects your device language and lets you switch live anytime: Deutsch, English, Français, Español, Italiano, Português, Nederlands, Polski, Čeština, Slovenčina, Magyar, Română, Türkçe, Русский, Українська, Ελληνικά, Svenska, Dansk, 日本語, 中文. Perfect for a coffee break, a train ride, or winding down after work. Slide, combine, win. DuoDom — side by side, gone for good.
